The dynamic mechanisms about slag skim during top lance blowing gas skimming slag process are analyzed by 1 :6 water model test
and the effect of blowing gas rate ( 10-30 L/min)
lance submerged depth (90-270 mm) and lance location ( distance from edge 0-160 mm) on slag skimming results has been tested and studied. Results show that with increasing blowing gas rate and top lance submerged depth and reducing the distance between the submerged location of lance and the hot metal ladle back wall
the results of slag skimming are obvious improvement
it is available to skim slag on hot metal. Commercial application pilot production results show that with using top-blowing auxiliary skimming slag process the slag skimming time is markedly reduced
